[0059]
By the way, the present invention is not confined to have the CD in these three districts especially.For example, even do not have Lead-In Area 101, leading-out zone 103 or mesozone 104, also can construct the data structure of following explanation.In addition, as described later, can further carry out segmentation to Lead-In Area 101, leading-out zone 103 or mesozone 104.
[0060]
Shown in Fig. 1 (b), the CD 100 among this embodiment has such structure, and the L0 layer and the L1 layer of an example that has promptly constituted " first and second recording layers " of the invention described above is laminated to respectively on the transparent substrates 106.When this two stratotype CDs 100 are carried out recording/reproducing,, carry out the recording/reproducing in L0 layer or the L1 layer according to having the focal position that shines the laser LB of upside from the downside of Fig. 1 (b) on which recording layer.In addition, the CD 100 among this embodiment is not limited to two-layer one-sided type double deck type just, and can be the just double-deck bilateral type of two-layer bilateral type.In addition, the CD 100 among this embodiment is not limited to the above-mentioned CD with two recording layers, and can be the multi-layered type CD with three layers or multilayer.
[0061]
By the way, will discuss to recording/reproducing process of carrying out according to opposite way on the two stratotype CDs and every layer data structure subsequently.
[0062]
(1-2) detailed structure
Next, referring to figs. 2 to Fig. 4, will discuss to two stratotype optical disc data structures among the embodiment of information recording carrier of the present invention.More particularly, referring to figs. 2 to Fig. 4, will be to two stratotype optical disc data structures, constituted the physical sector number (being called " sector number " when need opportunity hereinafter) of the ECC piece in the video disc recording district and discuss according to record or playback procedure that the opposite way of CD is carried out.Fig. 2 shows two stratotype optical disc data structures among the embodiment of information recording carrier, constituted the physical sector number of the ECC piece in the video disc recording district and according to the record of the opposite way of CD or the concept map of playback method.Fig. 3 shows two stratotype optical disc data structures among the embodiment of information recording carrier, constituted the physical sector number of the ECC piece in the video disc recording district and according to the record of the opposite way of CD or another concept map of playback method.Fig. 4 shows the data field of a specific example of the position that is used to specify the section among the present invention and the enlarged diagram of representing the address of this position.By the way, the longitudinal axis among Fig. 2 to Fig. 4 is represented the represented sector number of sexadecimal numeration, and transverse axis is illustrated in the relative position on the disc radial direction.
[0063]
As shown in Figure 2, two stratotype CDs 100 among the embodiment of information recording carrier of the present invention have two recording layers that are laminated on the unaccounted substrate, i.e. L0 layer and L1 layer.
[0064]
Specifically, to outer circumferential sides, the L0 layer has from inner circumferential side: be used for optimal recording power (calibration process: OPC: best power control) the power calibration area 105-0 (abbreviating " PCA " when needing hereinafter as) that detects; Recordng management area 106-0 (abbreviating RMA when needing hereinafter as); Lead-In Area 101-0; Data field 102-0; And mesozone 104-0.In addition, the arrow among the PCA 105-0 is expressed as the direction of carrying out calibration process and consuming recording areas.
[0064]
In RMA 106-0 (and described subsequently 106-1), can write down the RMD (record management data) of an example that has constituted " management information " of the present invention.Specifically, in RMA106-0 (106-1), can additionally write down or about 700 times of write-once RMD.
[0066]
RMD roughly comprises following four kinds of different information; That is to say, (i) be used for identification number information, promptly so-called driving id information (driving identification information) the information recording/playing back device of CD 100 executive loggings operation; (ii) as driving the numerical information of the optimal recording power that is detected that the specified information recording/playing back device of ID carries out the result of calibration process; (iii) disc status information, this disc state information representation (iii-1) not recording status, (iii-2) executed make information recording carrier can not carry out the state that write-once maybe can not be carried out the finalization processing of addition record, perhaps executed such as state of the such recording mode of incremental record mode or the like; And (iv) zone field.By the way, in Fig. 5, will be discussed in detail subsequently (iv) zone field.
[0067]
Lead-In Area 101-0 has control data section CDZ.In control data section CDZ, for example utilized laser or the like prerecord such as the number of recording layer, the direction and the so various information of track space of track record.
[0068]
In the 102-0 of data field, can carry out record to recorded information.Particularly, in the data field of CD 100 in this embodiment, can be by being that record cell comes recorded information is carried out record with the section among the present invention.By the way, in Fig. 4, section is gone through subsequently.
[0069]
Mesozone 104-0 has and can prevent from L0 layer and L1 layer are write down or the position deviation reset such basic function to not recording areas and the substrate.The function that also has so-called " jump buffer zone ", this function can prevent that when layer jumps record or replay position from deviating to not outside the recording areas and substrate.By the way, a specific example of " fixedly buffer zone " of the present invention is formed by mesozone 104-0 (and described subsequently mesozone 104-1) structure.
[0070]
On the other hand, to inner circumferential side, the L1 layer has from outer circumferential sides: mesozone 104-1; Data field 102-1; Leading-out zone 103-1; RMA106-1; And PCA 105-1.More particularly, PCA 105-0 (105-1) and RMA 106-0 (106-1) integral body can be called " block of information ".In addition, above-mentioned Lead-In Area 101-0 (101-1), data field 102-0 (102-1) and mesozone 104-0 (104-1) integral body can be called " R-block of information ".
[0071]
Especially, in the CD 100 in this embodiment, for example according to as shown in Figure 3 incremental record mode or the like, if the data volume of recorded information relatively less than the whole recording capacity of CD, the excircle end of data field 102-0 (102-1) is positioned on the inner circumferential side so.In this case, from the excircle end of data field 102-0 (102-1) to the direction of outer circumferential sides, the mesozone 104s-0 (104s-1) that moves is provided.By the way, " variable buffer " of the present invention specific example is formed by mobile mesozone 104s-0 (104s-1) structure.
[0072]
Two stratotype CDs 100 are to construct in the manner described above, therefore CD 100 is being write down or playback time, optical pickup apparatus by the information recording/playing back device in the specific example of described information record carrier of the present invention subsequently or the like, laser LB is irradiated from a side of unaccounted substrate, that is to say in Fig. 2 and Fig. 3 to shine upside, and its focal length or the like is controlled from downside.Simultaneously, displacement and the direction that the footpath at CD 100 is made progress controlled.By this, data recording is reset in each recording layer or to record data.
[0073]
For the record or the playback procedure of two stratotype CDs among the embodiment of information recording carrier of the present invention, adopt opposite way.Opposite way here is such mode, promptly when the record of two stratotype CDs or playback procedure, the optical pickup apparatus of described information recording/playing back device moves to outer circumferential sides from inner circumferential side in the L0 layer after a while, that is to say on the direction of arrow on the sensing right side in Fig. 2 and Fig. 3 and move, optical pickup apparatus moves to inner circumferential side from outer circumferential sides in the L1 layer simultaneously, that is to say on the direction of arrow on the sensing left side in Fig. 2 and Fig. 3 and move, thereby to two stratotype CD executive logging or playbacks.In opposite way, if record or playback in the L0 layer are through with, so when the record in the L1 layer or when resetting beginning, be positioned at optical pickup apparatus on the outermost circumference and needn't move to inner periphery once more, and it is just enough only to make focal length become the L1 layer from the L0 layer.Therefore, the transformation period of existence from the L0 layer to the L1 layer is than the short such advantage of parallel mode.Here it is in the process that a large amount of content informations are write down adopts the reason of opposite way.
[0074]
Specifically, shown in the diagram part of Fig. 2, at first, in the L0 layer, when optical pickup apparatus in Lead-In Area 101-0, data field 102-0 and mesozone 104-0 when inner circumferential side moves to outer circumferential sides, the sector number in the recording areas of CD 100 has increased.More particularly, optical pickup apparatus sequentially access sector number is the reference position (referring to the point of the B among Fig. 2) of the data field 102-0 of " 030000h " and the sector number end position (abbreviating " turning point " in the L0 layer in case of necessity hereinafter as: referring to the point of the C among Fig. 2) for the data field 102-0 of " 1AFFFFh " for the end position (referring to the point of the A among Fig. 2) of the Lead-In Area 101-0 of " 02FFFFh ", sector number, and optical pickup apparatus has moved to the mesozone 104-0 of impact damper effect, by record or the playback in this execution L0 layer.By the way, in this embodiment, " h " of the end of " 30000h " or the like represents that it is represented by sexadecimal number.On the other hand, in the L1 layer, specifically, when optical pickup apparatus in mesozone 104-1, data field 102-1 and leading-out zone 103-1 when outer circumferential sides moves to inner circumferential side, the sector number in the recording areas of CD 100 has increased.More particularly, the mesozone 104-1 of optical pickup apparatus access sequentially plaing impact damper effect, sector number are the end position (referring to the point of the E among Fig. 2) of the data field 102-1 of " FCFFEFh " for reference position (abbreviating " turning point " in the L1 layer in case of necessity hereinafter as: referring to the point of the D among Fig. 2) and the sector number of the data field 102-1 of " E50000h ", and optical pickup apparatus moves to leading-out zone 103-1, by record or the playback in this execution L1 layer.
[0075]
All sector numbers in above-mentioned L0 layer and the L1 layer have 15 the complement relation of sexadecimal number.More particularly, the turning point (sector number " E50000h ") in turning point in the L0 layer (sector number " 1AFFFFh ") and the L1 layer has 15 complement (complement number) relation.As pro forma content (As a formal matter), the complement of " 1AFFFFh " is to convert dyadic number " 000110101111111111111111 " to, bit inversion is " 111001010000000000000000 " and its " E50000h " of changing sexadecimal number again into obtained by the sector number " 1AFFFFh " with sexadecimal number.
[0076]
Therefore, when for example the sector number " E50000h " that moves to sector number " 1AFFFFh " and the data field 102-1 from the L1 layer continuously at the sector number " 030000h " of the data field 102-0 of optical pickup apparatus from the L0 layer moves to sector number " FCFFEFh " continuously, to writing down such as the such recorded information of content or resetting.
[0077]
With regard to above-mentioned physical sector number, distribute one to one or dispatch logic block address (LBA).More particularly, for example, " 000000 " LBA is corresponding with the sector number of " 030000h ", and " 17FFEF " LBA is corresponding with the sector number of " 1AFFFFh ".In addition, " 180000 " LBA is corresponding with the sector number of " E50000h ", and " 2FFFEF " LBA is corresponding with the sector number of " FCFFEFh ".Therefore, for example, principal computer can be according to for example coming executive logging and replay operations by the LBA (Logical Block Addressing) of file system management and needn't be known physical sector number.
[0078]
Especially, among the data field 102-0 and 102-1 of CD 100 in this embodiment, as shown in Figure 4, a section or a plurality of section be bridge joint and be positioned on two layers.By the way, in this embodiment, be expressed as a plurality of sections (wherein " n " is natural number) that data field 102-0 (102-1) is provided by " section #n ".
[0079]
Can utilize following four points to specify section #n among this embodiment.These four points are: (i) some Pn1 (sector number: Xn1), be used for representing the reference position of the section #n of L0 layer; (ii) put Pn2 (sector number: Xn2), be used for representing the end position of the section #n of L0 layer; (iii) put Pn3 (sector number: Xn3), be used for representing the present invention's recording areas and not edge between the recording areas or boundary position; And (iv) put Pn4 (sector number: Xn4), be used for representing the end position of the section #n of L1 layer.
[0080]
Specifically, on the inner circumferential side of a Pn1 and be used for representing providing on the outer circumferential sides of some F of reference position of section of L1 floor BSGA (piece synchronous protection district) (address of expression point F has the complement relation with the address of the some Pn2 that is used for representing this section)." BSGA " here is such recording areas, in this recording areas, utilize described subsequently information recording/playing back device for example will be used for realizing exactly that in the process of reading and recording information exactly various servo synchronizing signals (a so-called SYO signal) carry out record by the ECC module unit.In addition, the marginal position among the present invention can be arranged in L0 layer or the L1 layer of this section #n.In addition, marginal position is represented record position and the position in the not recording areas of opening entry information from then on, the specified position of promptly so-called NWA (but next write address).By the way, " edge address " of the present invention example is formed by the NWA structure.NWA can be represented by for example sector number or the like.
[0081]
The RMD that has constituted an example of " management information " of the present invention comprises the information that is used to represent above-mentioned sector number Xn1 to Xn4 as zone field, so that specify section #n.
[0082]

(2-2) principle of operation
Next,, and, the principle of operation of the information recording/playing back device among first embodiment of information record carrier of the present invention is discussed to Figure 16 with reference to figure 9 in case of necessity with reference to above-mentioned Fig. 8.Fig. 9 shows the performed use section of information recording/playing back device among the embodiment of information record carrier of the present invention as the recording operation of record cell and the process flow diagram of finally changing processing.Figure 10 has showed as the result's of a recording operation of the information recording/playing back device among the embodiment of information record carrier of the present invention record the synoptic diagram of the recording areas of section #1, section #2 or the like.Figure 11 shows the form with a specific example of the corresponding zone field of Figure 10.Figure 12 has showed as the result's of another recording operation of the information recording/playing back device among the embodiment of information record carrier of the present invention record the synoptic diagram of the recording areas of section #3, section #4 or the like.Figure 13 shows the form with another specific example of the corresponding zone field of Figure 12.Figure 14 shows information recording/playing back device in the embodiment of information record carrier of the present invention and has finished the record of recorded information and for example write down synoptic diagram such as the recording areas after the such file system of UDF bridge file system.Figure 15 shows the form with another specific example of the corresponding zone field of Figure 14.Figure 16 shows the synoptic diagram that information recording/playing back device in the embodiment of information record carrier of the present invention has been finished the recording areas after the finalization processing.By the way, if sector number is identical with segment number or the like in above-mentioned accompanying drawing, they carry the same numbers reference so, and save the explanation to it.
[0115]
As shown in Figure 9, if loaded CD 100, as initial operation, utilize under the control of the opertaing device such, to obtain so such as the such management information of RMD (step S101) such as CPU305 such as optical pickup apparatus 301 and signal record/reproducing device 302 such fetch equipments.
[0116]
After this, under the control of the opertaing device such, based on judging such as the such management information that is obtained of RMD whether CD 100 is in not recording status (step S102) such as CPU 305.If CD 100 is in not recording status (step S102: be), the RMD that will be in so under the determined in advance original state records among the RMA 106-0 (106-1) (step S103).On the other hand, as the judged result among the step S102, if CD 100 is not to be in not recording status (step S102: not), obtain up-to-date RMD from RMA 106-0 (106-1) so.
[0117]
After this, under the control of the opertaing device such, judge whether the recording status of section has changed (step S105) such as CPU 305.Specifically, in recording process for predetermined segment, judge whether to have sent " RESERVE TRACK/RZONE order (keeping track/RZONE order) ", so that predetermined segment is set to be in " keeping upstate (referring to Fig. 6 (c)) fully " or " part keeps upstate (referring to Fig. 6 (d)) " down from for example principal computer or the like.Perhaps, judge whether to have sent " CLOSETRACK/RZONE/SESSION/BORDER order (closing closed orbit/RZONE/ session/edge order) ", so that predetermined segment is set to be in " keeping down state (referring to Fig. 7 (a)) fully " or " part keeps down state (referring to Fig. 7 (b)) " from for example principal computer or the like.
[0118]
If the recording status of section has changed (step S105: be), so the RMD that upgrades is recorded among the RMA 106-0 (106-1) (step S106).On the other hand, if the recording status of section does not become (step S105: not), save step S106 so.
[0119]
After this, under the control of the opertaing device such, judge whether by being that record cell comes recorded information is write down (step S107) with the section such as CPU 305.If by being that record cell comes recorded information is write down (step S107: be) with the section, so for example come expectation section executive logging operation (step S108) according to the incremental record mode.Specifically, for example issue " write order " and when at every turn carrying out recording operation, the RMD that upgrades being recorded among the RMA 106-0 (106-1).On the other hand, if, save step S108 so not by being that record cell comes recorded information is write down (step S107: deny) with the section.
[0120]
After this, under the control of the opertaing device such, judge whether recorded information reset (step S109) such as CPU 305.If recorded information is reset (step S109: be), under the control of the opertaing device such, carry out replay operations (step S110) so such as CPU 305.If recorded information is not reset (step S109: deny), saves step S110 so.
[0121]
After this, under the control of the opertaing device such, judge whether to carry out finalization processing (step S111) such as CPU 305.If (step S111: not), operating process is got back to above-mentioned steps S105 so not carry out finalization processing.
[0122]

[0140]
After this, the buffered data to a part having constituted recorded information writes down (step S114) for finalization processing.More particularly, as shown in figure 16, it is recorded among mobile mesozone 104s-0 (104s-1), the Lead-In Area 101-0 and leading-out zone 103-1 of an example that has constituted " variable buffer " of the present invention.By the way, the band among Figure 16 (and described subsequently Figure 21) shows the zone of being write down for finalization processing.
[0141]
(3) to operation and the Research on effect of the embodiment of information recording carrier according to the present invention and information record carrier
Next, with reference to Figure 17 to Figure 21, consider operation and the effect of the embodiment of information recording carrier of the present invention and information record carrier.The enlarged diagram of the address of this position is represented in the data field and being used to that Figure 17 shows a specific example of the position that is used to specify section in the comparative example.Figure 18 shows the form of the data structure of the zone field within the RMD of an example that is included in " management information " that constituted comparative example.Figure 19 show the information recording/playing back device in the example as a comparison a recording operation result record the synoptic diagram of recording areas of section # 1, section # 2 or the like.Figure 20 shows information recording/playing back device in comparative example and has finished the record of recorded information and for example write down synoptic diagram such as the recording areas after the such file system of UDF bridge file system.Figure 21 shows the synoptic diagram that information recording/playing back device in the comparative example has been finished the recording areas after the finalization processing.
[0142]
As shown in figure 17, data field 102-0 on the CD in the comparative example 100 and 102-1 have and are the defined section of each layer or a plurality of section.In other words, the section #n in the comparative example comes appointment by following two points.That is to say, can be by the some Pn1 (sector number: the some Pn2 (sector number: Xn2) specify of Xn1) and (ii) representing the end position of section #n of the reference position of the section #n in the recording layer of (i) expression L0 layer or L1 layer.
[0143]
Therefore, as shown in figure 18, the data structure of the RMD in the comparative example is identical with this embodiment basically; Yet, can specify a section #n by the data volume of 8 bytes." the section # 2 " that more particularly, as shown in figure 19, will be in " the section # 1 " under " keeping upstate (referring to Fig. 6 (c)) fully " and be under " complete state (referring to Fig. 7 (c)) " is recorded among the 102-0 of data field." the section # 3 " that will be in addition, under " unidentified state (referring to Fig. 6 (a)) " is recorded on the outer circumferential sides of " section # 2 ".After this, as shown in figure 20, be after a series of processing of recording operation or the like of record cell with the section in the comparative example having finished, will be recorded in " section # 1 " such as the such file system of UDF bridge file system.In addition, recorded information is recorded in " section # 2 " extremely in " section #n ".
[0144]
Yet, on the information recording carrier in comparative example, as shown in figure 21,, must carry out redundancy ground record to the buffered data of a part having constituted recorded information for finalization processing.More particularly, buffered data is recorded among mobile mesozone 104s-0 (104s-1), Lead-In Area 101-0 and the leading-out zone 103-1.In addition, in comparative example, must record section # 1 with the L0 layer to the recording areas of 1 layer of section #n opposing L such as the such record ignored information of pseudo-data.
[0145]
As mentioned above, on the information recording carrier in comparative example, except such as the such effective recorded information of content information, for example also must record in the not recording areas with 1 layer of the recording areas opposing L of L0 layer such as the such gibberish of pseudo-data " Null ".This is because the section during the coke charge point to optical pickup apparatus jumps when general DVD-ROM driver is carried out replay operations (layer change) is servo normally to be controlled, thereby user data is normally reset.Therefore, except such as writing time of the so effective recorded information of content information the length,, carry out actual finalization processing and will spend the more time also because length writing time of gibberish.
[0146]
Specifically, this is that servo owing to there not being the RF replay signal to end section so if optical pickup apparatus enters wherein, this can cause out of control because it be not recorded under the situation about pseudo-data not being write down on the inner circumferential side of L1 layer for example.Specifically, for example, at first carry out under the situation about focusing on the L1 layer at the optical pickup apparatus of DVD-ROM driver, that is to say at coke charge point under the situation of jump (layer change), for the predetermined sector the L0 floor from two stratotype CDs number (for example " X0 ") is carried out access to the target sector in the L1 floor number (for example " Y1 "), if in the L1 layer promptly be exactly the sector number (for example " Z1 ") of the coke charge point destination of jumping be Unrecorded, for example can't control optical pickup apparatus under servo according to the section that differs (phase difference) method so, this can cause out of control.More particularly, the optical pickup apparatus of only playback type of the DVD-ROM driver of employing phase difference method is difficult under section is servo or can't controls the not recording areas on the DVD-R that adopts push-pull method at all.In addition, this is by using an example of the situation that the DVD-ROM driver can not reset to the information on the DVD-R.
[0147]
In contrast, according to referring to figs. 1 to the information recording carrier of the present invention that Figure 16 discussed and the embodiment of information record carrier, by being record cell with bridge joint at the section on two-layer, the inner circumferential side from each of L0 layer and L1 layer is sequentially carried out record to recorded information.Therefore, can make the recording areas that has write down of the recording areas that has write down of L0 layer and L1 layer impartial basically.
[0148]
Therefore, the time span of carrying out finalization processing is substantially equal to the time span that writes down such as the so effective recorded information of content information.Therefore, compare with comparative example, can greatly shorten length writing time, thereby help comfortableness of improving the user or the like, this is significantly favourable.More particularly, if as above-mentioned recorded information shown in Figure 16 have the data capacity littler than CD, be enough to make the outer circumferential sides of for example mobile mesozone 104s-0 (104s-1) to be in not under the recording status (being mirrored state) so.
[0149]
In addition, section of the present invention can come appointment by having RMD with the essentially identical data structure of traditional RMD, so this is extremely preferred.
